Lucky Stars: Kelly Rowland in Graphic Black and White

Former Destiny's Child member Kelly Rowland commanded the crowd with her sultry voice and rhythmic moves at a Courvoisiology Lab launch in midtown New York City last Thursday night. And as if her performance of throwback hits like "Survivor" and "Say My Name" weren’t enough to earn the diva some R-E-S-P-E-C-T, her outfit won high marks too. Amidst the stage lights, Kelly sparkled—literally—wearing chunky crystal accessories with her black button-up and chic wide leg white trousers by Rachel Zoe. She left the top unbuttoned just enough to expose a hint of her lacy black La Perla bra, resulting in an ensemble that was both sexy and sophisticated.
